Polyaluminium Chloride white powder
Polyaluminium chloride is a chemical product. It is divided into industrial grade and food grade. Industrial grade PAC is brown or yellow granule or powder. Food grade PAC is light yellow or white powder. The basicity of the Polyaluminium chloride is between 40 and 90. Our Polyaluminium chloride is usually used for all kinds of waste water treatment. And now the price is the most economic, because our company has made an adjustment in price. So if you need, please feel free to contact me!
Product Description
White polyaluminum chloride is a white or milky white milk powder fine powder processed by spray drying aluminum hydroxide powder and high-purity hydrochloric acid, and it is easy to melt when exposed to the air. The aqueous solution of this product is clear and transparent without any color, while the ordinary polyaluminum chloride aqueous solution is yellow or brown in color.

Application of white polyaluminum chloride
1. It is mainly used for the treatment of drinking water, industrial water supply, oilfield reinjection water, circulating cooling water and various sewage (such as urban domestic sewage, oily sewage, printing and dyeing sewage, papermaking sewage, steel mill sewage, etc.).
2. Paper sizing precipitant, sugar decolorization clarifying agent.
3. Used in many fields such as leather tanning, medicine, cosmetics and precision casting.
White polyaluminum chloride has replaced aluminum sulfate as a neutral sizing precipitant in the paper industry. Compared with aluminum sulfate, white polyaluminum chloride has the following characteristics:
1) A large number of positively charged and stable polynuclear aluminum complexes can effectively promote flocculation and sizing.
2) The appearance is white, and the iron content is extremely low, which can meet the needs of making high-quality paper.
3) Polyaluminum chloride is the pre-hydrolyzate of aluminum chloride, the degree of hydrolysis is relatively low, and the decrease of pulp pH value is smaller than that of aluminum sulfate.
4) Aluminum sulfate is only suitable for acid sizing, while polyaluminum chloride can be used for sizing in acidic and neutral environments, the corrosion of the system is significantly weakened, and the treatment of white water is easier.
5) It can be filled with cheap calcium carbonate filler, which not only reduces the production cost, improves the whiteness and folding resistance of the paper, but also overcomes the inevitable shortcomings of synthetic rubber materials (such as AKD, etc.) (such as slipping, sizing, etc.) uncontrollable, etc.).
6) Using polyaluminum chloride for sizing, the retention and drainage effects of the slurry are significantly improved.
7) Except for the breakage length of the paper performance, all other indicators are improved to varying degrees.
About the packaging of polyaluminum chloride.
Polyaluminum chloride is usually packed in 25kg pp bags or paper-plastic composite bags. Of course, we are mainly customer-centric and pack according to customer requirements.
About the lead time of PAC.
Within 7 working days after receiving the payment.
About shop of polyaluminum chloride.
The shelf life of PAC is two years. Do not stack more than 20 layers. Store in a cool, dark, ventilated, dry place, away from moisture.
